Freight class
The four freight-class factors
NMFC considers density, handling, stowability, and liability. Density describes weight relative to space; the other characteristics address how easily and safely a carrier can move and transport the goods.
Gather all four kinds of evidence
A reliable classification review begins with the commodity identity and its shipping preparation. Measure weight and dimensions, but also document whether the load is unusually long, unstable, fragile, hazardous, valuable, or difficult to place beside other freight. Record any details that may be needed to interpret the applicable NMFC provision.
What to check
- Capture the complete packed dimensions and weight.
- Describe packaging, palletization, and mechanical-handling access.
- Note unusual shape, overhang, stackability, and compatibility with other freight.
Important: the four characteristics inform classification, but the operational result is the class assigned by the correct current NMFC item and applicable provisions.
